Somehow, we ended up with a number of likely UDFA running backs on top of this year's Speed Scores, led by Damien Williams of Oklahoma. There will be a Matt Waldman column soon on the four top Speed Score guys and their strengths and weaknesses. Meanwhile, top prospect Ka'Deem Carey of Arizona had a Speed Score of 84.8, which would be the lowest ever for a player chosen in the first three rounds of the draft who wasn't immediately moved to wide receiver. (Hi, Dexter McCluster.)

I don't understand why 40 times are seemingly given so much weight. I'm still scratching my head as to how Tyler Gaffney ran a faster 40 than De'Anthony Thomas. Either the sample size is too small, or Gaffney has better track technique, or maybe running without pads is distorting the times, but no way in the world is Gaffney faster on the football field than Thomas.

He weighed 266 and ran a 4.53, so his speed score would be (266*200)/4.53^4 =126.3. Goddamn. If you use his unofficial time of 4.47, his score jumps to 133.3. I wonder where that ranks on the all-time list.
